The engine revs very erratically when the car is at idle (1,100-1,300 RPMs, ) and occasionally when driving hits, a very high RPMs (4,000-5,000 RPMs). I have cleaned the throttle body and checked for leaks on the air intake system. The car has an i.6 SR engine.

This sounds like the engine misfiring, but I can tell for sure if you upload a video in your response of the engine having the problem. Also is the check engine light on? If so, let's run the codes to see what comes up. This guide can help us get started on fixing your car:
